The main objectives of this note are to point out some strengths and some limitations of Kirkwood’s algebraic method for decision problems, and to propose a modification to address the limitations. The modification is based on the valuation network technique, and it enables us to better relate Kirkwood’s method to the graphical techniques of valuation networks and influence diagrams.

Several real options analysis techniques designed for practitioners exist in literature, but there is discrepancy in their underlying assumptions, mechanics and applicability. Within this paper, a review of approaches targeted towards practitioners is included, and a novel way of integrating market and private uncertainties is proposed. Market risk is incorporated into the dynamics of the proje...

JOHN QUIGGIN Department of Economics James Cook University People express concern about the possible extinction of animal species which they will never see, about damage to wilderness areas they will never visit, and so on. Such concerns are often interpreted by economists in terms of ‘existence’ or ‘passive use’ values. Three views have been proposed regarding the appropriate way of dealing wi...

Information security risk management is a fundamental process conducted for the purpose of securing information assets in an organization. It usually involves asset identification and valuation, threat analysis, risk analysis and implementation of countermeasures. A correct asset valuation is a basis for accurate risk analysis, but there is a lack of works describing the valuation process with ...

The valuation of American Options can often be reduced to the study of a free boundary value problem for a partial differential equation. This paper will discuss how the Method of Lines (MOL) can be used to study the numerical valuation of American Options and to determine the early exercise frontier. This method is flexible, accurate and computationally fast.

Asset analysis and valuation are important parts of the information security risk management. Outputs they produce are used in the process of risk analysis that plays a key role in securing organization’s business processes. A correct analysis and valuation of assets should reveal not only their importance for the organization, but also their relationships and dependencies between each other. T...

Classical conservation approaches focus on the man-made degradation of ecosystems and tend to neglect the socialecological values that human land uses have imprinted on many environments. Throughout the world, ingenious land-use practices have generated unique cultural landscapes, but these are under pressure from agricultural intensification, land abandonment, and urbanization. In recent years...
